WRENCH.

To all whom it may concern:

Be it known that I, .Tosnrn O. LALoNnE, a subject of the King of GreatBritain, residing in the city and district of Montreal, in the Provinceof Quebec, Canada, have invented certain new and useful Improvements inWrenches; and I do hereby declare that the following is a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. I

My invention relates to ratchet wrenches; the object of my invention isto provide a ratchet wrench with a removable head having nut receivingrecesses adapted to engage over a nut from a direction either parallelor transverse to its axis; a further object is to provide an easilyoperated means for normally maintaining a removable head in position;and, my invention consists of the construction, combination andarrangement of parts as herein illustrated and described, characterizedby a bifurcated retaining head, having therein a ratchet head normallymaintained in position by means of a slidable spring actuated retainingplate.

In the accompanying drawings, forming part of this application, I haveillustrated one form of embodiment of my invention, in whichdrawings'similar reference characters designate corresponding parts, andin which:

Figure 1 is a plan view of one side of the wrench; Fig. 2 is a plan viewof the same side of the wrench, with the ratchet head retaining plateremoved; Fig. 3 is a plan view of the opposite side of the wrench; Fig.4 is a transverse section on line 4-4 of Fig. 3, looking in thedirection indicated by the arrow; Fig. 5 is a perspective of a pawl andspring; and Fig. 6 is a perspective of a ratchet head retaining plate.

Referring to the drawings, 1 designates a handle having an integralbifurcated expanded head 2, which is cut away to form an approximatelyround socket 3, having a flange 4. i

Re vably disposed in the socket 3, and adapted to re ate on the flange4, is a toothed ratchet head 5, provided with recesses 6 adapted'toengage the nutto be turned, which recesses extend from the peripherytowards the center of the ratchet head, so that the walls of therecesses may be passed over the faces of a nut when the wrench isinserted from a point either transverse or parallel to the axis of thenut. The periphery of the removable head 5' is provided with teeth 7Adjacent the wall of the socket 3, the head 2 of the wrench is providedwith recesses 8, in which are rockably disposed the pawls 9, which arenormally maintained in engagement with the teeth 7 by means of the flatsprings 10 carried by the pawls and bearing against Y the walls of therecesses 8. The pawls 9 are both set in the same direction, so as toprevent rotation of the head 5 in one direction, and to force the headin an opposite Specification of Letters Patent.

direction when the handle is reciprocated and the recesses 6 are engagedwith a nut.

Slidably disposed on the handle is a bifurcated retaining member 11,-the bifurcated portion of which normally extends over the head 5, and isadapted to retain the head within the socket 3. The rear end of theslidable plate 11 is provided with cars 12, adapted to engage over thehandle 1 and to act asa guide for the plate. Centrally of its length,the platell is provided with a slot 13, having a flange l4 projectingtherein.- Disposed through the slot 13, and secured to the handle 1, isa headed guide member 15, the under surface of the head of which bearson the fiange l i, so that the head is flush with the upper surface ofthe plate 11.

A spring 16 has one end secured to the handle 1, and has its oppositeend secured to the plate 11, so that the tension of the spring normallymaintains the bifurcated end of the plate 11 over the ratchet head 5, sothat said head .2 are provided with projecting cars 18, under which theremovable head is adapted to be inserted, and when so inserted undersaid cars is adapted to be held in operative positionby means of theslidable plate 11.

When it is desired to turn a nut in an opposite direction to the one inwhich it would be turned by the arrangement described, the wrench issimply reversed. The head 5 may be made in any number with differentsizes of recesses 6, so as to adapt the wrench to use in connection withnuts of any size.

.Having thus fully described my invention, what 1 claim as new anddesire to secure by Letters Patent is:

1. In a. wrench, the combination comprising a handle having a bifurcatedexpanded head formed with a flange and termed with cars projecting overthe flange, a removable ratchet head'disposed on the flange and underthe ears and provided with nut engaging recesses and extend ing from itsperiphery, slidable means for maintaining the ratchet head on the flangeand under the ears, and means for rotating the ratchet head withrelation to the handle.

2. In a wrench, the combination comprising a handle, having a headformed with a'socket open at one side, a

removable ratchet head disposed in the socket and prow vided with nutengaging recesses adapted to register with the open side of the socket,a slidable member disposed over the ratchet head, and means for rotatingthe ratchet head with relation to the handle."

3. In a wrench, the combination comprising a handle having a head formedwith a socket a portion of the wall of which is removed, a removableratchet head disposed in the socket and provided with nut engagingrecesses in its periphery, a spring actuated member disposed over theratchet head, and means for rotating the ratchet head with relation tothe handle.

4. In a wrench, the combination comprising a handle having a bifurcatedhead, a removable rotatable ratchet head carried by the bifurcated headand provided with nut engaging recesses, means for rotating the ratchethead in one direction and for preventing its reverse rotation, a plateprovided with ears adapted to engage the handle, and provided with aslot, said plate extending over said ratchet head, a guide memberdisposed in the slot, and a spring secured to the handle and the plate.

5. In a wrench, the combination comprising, a handle having a sockettherein, a removable rotatable ratchet head carried in the socket andprovided with nut engaging recesses, means for rotating and preventingreverse rotation of the ratchet head, a plate slidably disposed on thehandle and projecting over the ratchet head, and provided with a centralslot having a flange projecting therein, a headed guide member disposedthrough the slot, bearing on the flange, and secured to the handle, anda spring secured to the handle and the plate, and adapted to normallymaintain the plate over the ratchet head.

6. In a wrench, the combination comprising a handle having a sockettherein, a. removable rotatable ratchet head carried in the-socket andprovided with nut engaging recesses, means for rotating and preventingreverse rotation of the ratchet head, a plate slidably disposed on thehandle and projecting over the ratchet head, and provided with a centralslot having a flange projecting therein, a headed guide member disposedthrough the slot, bearing on the flange, and secured to the handle, anda spring secured to the handle and the plate, and adapted to normallymaintain the plate over the ratchet head, and said plate having aprojecting lip.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
